Hospital service areas – a new tool for health care planning in Switzerland

Gunnar Klauss; Lukas P. Staub; Marcel Widmer; André Busato

BackgroundThe description of patient travel patterns and variations in health care utilization may guide a sound health care planning process. In order to accurately describe these differences across regions with homogeneous populations, small area analysis (SAA) has proved as a valuable tool to create appropriate area models. This paper presents the methodology to create and characterize population-based hospital service areas (HSAs) for Switzerland.MethodsWe employed federal hospital discharge data to perform a patient origin study using small area analysis. Each of 605 residential regions was assigned to one of 215 hospital provider regions where the most frequent number of discharges took place. HSAs were characterized geographically, demographically, and through health utilization indices and rates that describe hospital use. We introduced novel planning variables extracted from the patient origin study and investigated relationships among health utilization indices and rates to understand patient travel patterns for hospital use. Results were visualized as maps in a geographic information system (GIS).ResultsWe obtained 100 HSAs using a patient origin matrix containing over four million discharges. HSAs had diverse demographic and geographic characteristics. Urban HSAs had above average population sizes, while mountainous HSAs were scarcely populated but larger in size. We found higher localization of care in urban HSAs and in mountainous HSAs. Half of the Swiss population lives in service areas where 65% of hospital care is provided by local hospitals.ConclusionHealth utilization indices and rates demonstrated patient travel patterns that merit more detailed analyses in light of political, infrastructural and developmental determinants. HSAs and health utilization indices provide valuable information for health care planning. They will be used to study variation phenomena in Swiss health care.

Background: This project is part of an evaluation of complementary and alternative medicine (CAM) aimed at providing a scientific basis for the Swiss Government to include 5 CAM methods in basic health coverage: anthroposophic medicine, homeopathy, neural therapy, phytotherapy and Traditional Chinese Medicine (TCM). Objectives: The objective was to explore the philosophy of care (convictions and values, priorities in medical activity, motivation for CAM, criteria for the practice of CAM, limits of the used methods) of conventional and CAM general practitioners (GPs) and to determine differences between both groups. Materials and Methods: This study was a cross-sectional survey of a representative sample of 623 GPs who provide complementary or conventional primary care. A mailed questionnaire with open-ended questions focusing on the philosophy of care was used for data collection. An appropriate methodology using a combination of quantitative and qualitative approaches was developed. Results: Significant differences between both groups include philosophy of care (holistic versus positivistic approaches), motivation for CAM (intrinsic versus extrinsic) and priorities in medical activity. Both groups seem to be aware of limitations of the therapeutic methods used. The study reveals that conventional physicians are also using complementary medicine. Discussion: Our study provides a wealth of data documenting several aspects of physicians’ philosophy of care as well as differences and similarities between conventional and complementary care. Implications of the study with regard to quality of care as well as ethical and health policy issues should be investigated further.

Over the past few years, a considerable increase in complementary and alternative medicine (CAM) has been observed, particularly in primary care. In contrast little is known about the supply of CAM in Swiss hospitals. This study aims at the investigation of amount and structure of CAM activities of Swiss hospitals. Materials and Methods: We designed a cross-sectional survey using a 2-step, questionnaire- based approach acquiring overview information form hospital managers in a first questionnaire leading to detailed information on CAM usage at medical department level (head of department). This second questionnaire provides data of physician-based and non-physician-based CAM supply. Results: The size of hospitals was significantly associated with the provision of CAM. 33% of the hospital managers indicated 1 or more medical doctor (MD) using CAM in their hospital compared to 37% of confirmation on department level (Kappa value 0.5). Mostly different CAM methods were applied. Acupuncture was used most frequently. However only 13 hospitals (11%) occupied more than 3 CAM MDs and only 5 hospitals had more than 2 full-time equivalents for MDs. Furthermore, 74.7% of these personnel resources were dedicated for outpatient care. In terms of CAM methods anthroposophic medicine accounted for more than half of the total personnel costs. On the other hand usage of non-physician based CAM accounted for 41% according to hospital managers compared to 64% of CAM usage according to medical departments (Kappa values 0.31). Reflexology of the foot was used most frequently. Conclusion: Total supply of CAM in Swiss hospitals is low and concentrates on few hospitals. Acupuncture is the widest spread discipline but anthroposophic medicine spends the most resources. The study shows that a high patient demand for CAM faces low supply in hospitals.

Complementary and Conventional Medicine in Switzerland: Comparing Characteristics of General Practitioners

Marcel Widmer; Sylvia Herren; Andreas Dönges; Florica Marian; André Busato

Objectives: Do structural characteristics of general practitioners (GPs) who practice complementary medicine (CAM) differ from those GPs who do not? Assessed characteristics included experience and professional integration of general practitioners (GPs), workload, medical activities, and personal and technical resources of practices. The investigated CAM disciplines were anthroposophic medicine, homoeopathy, traditional Chinese medicine, neural therapy and herbal medicine. Material and Methods: We designed a cross-sectional study with convenience and stratified samples of GPs providing conventional (COM) and/or complementary primary care in Switzerland. The samples were taken from the database of the Swiss medical association (FMH) and from CAM societies. Data were collected using a postal questionnaire. Results: Of the 650 practitioners who were included in the study, 191 were COM, 167 noncertified CAM and 292 certified CAM physicians. The proportion of females was higher in the population of CAM physicians. Gender-adjusted age did not differ between CAM and COM physicians. Nearly twice as many CAM physicians work part-time. Differences were also seen for the majority of structural characteristics such as qualification of physicians, type of practice, type of staff, and presence of technical equipment. Conclusion: The study results show that structural characteristics of primary health care do differ between CAM and COM practitioners. We assumed that the activities of GPs are defined essentially by analyzed structures. The results are to be considered for evaluations in primary health care, particularly when quality of health care is assessed.

The study systematically describes the frequency and geographic variability of major surgical interventions for musculoskeletal disorders in Switzerland. Age- and sex-standardized rates for joint replacements, arthroscopies, spine surgery and hip fracture repair were calculated for hospital service regions. Various statistical analyses were used to measure the extent of variation. The authors argue that the surgery of hip fractures can be used as index surgery in the context of analyzing variations in orthopedic surgery. Temporal trends imply that patient demand and supply factors related to clinical ambiguity and non-medical incentives of providers are far more important components leading to increased use than the sole effect of an aging population.

Analysis of patient flows for orthopedic procedures using small area analysis in Switzerland

Klazien Matter-Walstra; Marcel Widmer; André Busato

BackgroundIn general cantons regulate and control the Swiss health service system; patient flows within and between cantons are thereby partially disregarded. This paper develops an alternative spatial model, based upon the construction of orthopedic hospital service areas (HSAOs), and introduces indices for the analysis of patient streams in order to identify areas, irrespective of canton, with diverse characteristics, importance, needs, or demands.MethodsHSAOs were constructed using orthopedic discharge data. Patient streams between the HSAOs were analysed by calculating three indices: the localization index (% local residents discharged locally), the netindex (the ratio of discharges of nonlocal incoming residents to outgoing local residents), and the market share index (% of local resident discharges of all discharges in local hospitals).ResultsThe 85 orthopedic HSAOs show a median localization index of 60.8%, a market share index of 75.1%, and 30% of HSAOs have a positive netindex. Insurance class of bed, admission type, and patient age are partially but significantly associated with those indicators. A trend to more centrally provided health services can be observed not only in large urban HSAOs such as Geneva, Bern, Basel, and Zurich, but also in HSAOs in mountain sport areas such as Sion, Davos, or St.Moritz. Furthermore, elderly and emergency patients are more frequently treated locally than younger people or those having elective procedures.ConclusionThe division of Switzerland into HSAOs provides an alternative spatial model for analysing and describing patient streams for health service utilization. Because this small area model allows more in-depth analysis of patient streams both within and between cantons, it may improve support and planning of resource allocation of in-patient care in the Swiss healthcare system.

Satisfaction with Primary Health Care in Patients with Upper Respiratory Tract Infection: A Three-Level Approach

Franziska V Schoeni-Affolter; Klazien Matter-Walstra; Marcel Widmer; André Busato

Background: Upper respiratory tract infections (URTI) are common conditions for which individuals seek health care. The present study analyzes the satisfaction of URTI patients with general practitioners offering conventional treatment, alternative treatment, or a combination of both. Patients and Methods: Patients’ satisfaction with care was evaluated based on concepts of structure, process and outcome. Data were drawn from a nationwide cross-sectional survey, conducted in Switzerland, which evaluated conventional (COM) and complementary and/or alternative medicine (CAM). Participating physicians provided information about care structure. A questionnaire filled in by doctors and patients in parallel during the first visit provided information about the process of care (e.g. patients’ general health, duration and severity of symptoms, co-morbid conditions, diagnostic/therapeutic procedures and consultation time). One month later, patients completed a second questionnaire on their subjective disease- and treatment-related health status, beliefs and fulfilment of expectations, and treatment effects (outcome). Results: Structural and procedural differences were found. The most striking was the significantly longer consultation time with CAM physicians. Patients’ satisfaction as an outcome variable, however, did not differ between the different treatment approaches. Conclusions: General practitioners, offering a variety of treatments, accommodate an important demand in primary health care. Regardless of differences in structure and procedure of the practice types, patients perceive equal benefits of treatment after one month. Nonetheless, possible long-term effects of longer consultations in CAM practices, such as a possibly more stable long-term amelioration of health, have to be carefully evaluated in future studies with the same study design.
